Also called digital eye strain, computer vision syndrome refers to a group of problems related to the eye and vision caused by extended exposure to digital devices. Its symptoms tend to worsen the more you use computers, tablets, or smartphones. Many Americans are prone to this eye issue since they spend around seven hours a day working on a computer.
Read on to learn what causes computer vision syndrome and how to prevent it from a local optometry specialist.
Computer Vision Syndrome
Your eyes work harder than usual when you are using a digital device. The high visual demands increase the likelihood of a person to experience vision-related symptoms. Among the most common symptoms related to computer vision syndrome are eye strain, headaches, dry eyes, blurred vision, and neck and shoulder pain.
Uncorrected vision problems can worsen digital eye strain symptoms. Visit your eye doctor regularly for a comprehensive eye exam to ensure you are wearing an updated prescription or the correct eyewear. Viewing a digital screen is entirely different than reading printed materials. The text on your screen is usually not as contrasted as in print, and there could be the presence of glare or reflections, which could make viewing more challenging.
How to Avoid It
Choose a chair that can support your back and allow you to sit up straight comfortably. Your feet should rest flat on the floor, and chair arms should support your arms while typing.
The lighting in the room should not be causing glare or reflections on your screen. If there is glare, you can use low-wattage bulbs in desk lamps.
Proper Screen Position
You should be looking slightly downward when using your computer. The screen should be around 20 to 28 inches from your eyes, and the center of the screen should be about five inches below eye level.
Give Your Eyes a Break
Make blinking a habit, especially when using digital devices. You can follow the 20-20-20 rule as well to relax your eyes. All you need to do is look 20 feet away from the screen for 20 seconds every 20 minutes.
